Authorities say the 38-year-old Kyle was doing just that Saturday when he was slain along with a friend at a Texas gun range.

Police have charged 25-year-old Edie Ray Routh, of Lancaster, a former Marine, with murder in the deaths of Kyle and his friend 35-year-old Chad Littlefield.

Sgt. Lonny Haschel with Texas Department of Public Safety says Erath County deputies responded to a shooting at the Rough Creek Lodge on Saturday and found the bodies Kyle and Littlefield. Police have not said whether they have identified a motive in the case.
